It might be summer recess for New Jersey lawmakers, but Republicans aren’t taking a vacation from political attacks over the $32 billion budget that took effect this month.

The New Jersey Republican Party released a new radio ad Thursday faulting Democrats, who control both chambers of the Legislature, for not passing a budget with a guaranteed tax cut sought by Republican Gov. Chris Christie.

“Sadly, it’s the same old story from the Legislature. Billions for special interest spending. Not a dollar for tax cuts for New Jersey families,” the one-minute ad declares.

Democrats voted to set aside $183 million in the budget for a property-tax credit in 2013 if revenues this year meet expectations. Christie agreed to adopt the property tax credit instead of the 10% income tax cut he had originally sought, but the governor wanted it passed immediately within the budget.

Two anonymous speakers in the ad also attack Democrats for passing a budget with “special interest spending.” Democrats added $133 million to Christie’s spending plan for nursing homes, women’s health care and other priorities.

Christie vetoed the additional spending, arguing that it should be used immediately for a tax cut. He also vetoed a Democrat-backed bill to increase taxes on New Jersey residents earning more than $1 million.

The radio spot ends by urging listeners to call the Assembly Democratic office in Trenton to ask for a “bipartisan tax cut, now.”

Douglass Mayer, a spokesman for the state Republican Party spokesman, described the radio buy as “significant” but declined to disclose a dollar figure. “It’s time to give the Democrats in the Legislature a major reality check about their priorities,” he said.

Tom Hester Jr., a spokesman for the Assembly Democratic Majority Office, said that it was “beyond terrible” to call money for social services a form of special interest spending. He faulted Christie for vetoing the so-called millionaire’s tax, which would have paid for an additional property tax credit for seniors.

The ad is the latest in a series of efforts by Republicans to keep up the heat on the tax-cut issue after the governor signed the budget into law at the end of June. Christie and his fellow party members have vowed to crisscross the state in speaking to voters directly about the need for a guaranteed tax cut.

Earlier this month, the state GOP also released another radio ad featuring Christie speaking against the “Corzine Democrats.” The newly-coined term refers to former Gov. Jon Corzine’s decision to increase taxes on the state’s highest earners in 2009.

The first ad also encouraged residents to call Assembly Democrats. Hester said that they received “a few calls” after the radio spot.

“I’d say about half the calls we did receive actually vehemently opposed the governor and urged Democrats to continue their efforts to fight for middle-class property tax relief,” he said.
